IPC: H03K19/00
Filed: 1995-01-12
Abstract: PURPOSE: To provide an output driving circuit which can prevent the generation of an undesirable high-frequency signal without causing any unallowable delay. CONSTITUTION: An output driving circuit is provided with two output transistors M1 and M2 which connected in series between a power supply voltage Vcc and the ground, and two capacitors C1 and C2 connected between an output node N1 and the gates of the transistors M1 and M2. Acceleration circuits 12 and 22 are provided so as to quickly charge the gate voltages of the transistors M1 and M2 to their threshold voltages before an output transition takes place by supplying high voltages to the gates of the transistors M1 and M2 from the circuits 12 and 22. While the output signal of the driving circuit is in a transition, small currents are supplied to the gates of the transistors M1 and M2 by turning off the acceleration circuits 12 and 22. The capacitors C1 and C2, connected in phase opposition, prevent excessively abrupt changes of the voltage at the node n1.

Title: Power amplifying device
Inventor: KOJIMA HIROSHI
IPC: H03F3/30
Filed: 1995-01-13
Abstract: PURPOSE: To provide a power amplifying device which utilizes a device power source as effectively as possible and generates a small-distortion output signal. CONSTITUTION: A comparator 18 for level detection outputs a level detection signal when the voltage level of the output signal of an amplifier 14 exceeds a specific value, and a variable resistor 12 varies in attenuation quantity correspondingly to control the output signal from the amplifier 14 to a low level. Further, a comparator 16 for click detection generates a clip detection signal when the peak level of the output signal from the amplifier 14 exceeds a clip detection voltage and a variable resistor 12 varies in attenuation quantity correspondingly. Consequently, the maximum output power of the output signal can be held below the input electric power resistance of a load irrelevantly to a source voltage VCC, and even when a large input signal is applied to the amplifier 14, the output signal can be prevented from being distorted.
